These silicone door stoppers are one of those simple products that you don't realize you need until you have them - then you wonder how you lived without them! They're these clear, soft silicone bumpers that stick to your walls to protect them from door knobs slamming and causing damage. Each one is about 1.65 inches across and seriously thick at 0.31 inches, so they actually absorb impact really well. The self-adhesive backing is strong but doesn't leave residue when you remove them - which is great because I've moved them around a few times already. Installation couldn't be easier - just peel and stick to any clean, dry surface. No tools, no drilling, no mess. What's really impressive is how much quieter my house is now - no more loud banging every time a door closes! They're not just for doors either - I've used them on cabinets, the refrigerator, even on furniture that was bumping against walls. The transparent design is genius because they basically disappear once installed - no ugly hardware messing up your decor. The silicone is waterproof and reusable too - just wash with water and let dry if you need to move them. For renters especially, these are a lifesaver for preventing damage deposits. Seriously, at this price for six protectors, it's one of the best home improvement investments I've made recently!
